I ordered these to replace the old tuning pegs on my 90's Korean Hamer Archtop.
They fitted perfectly into the tuner holes. But I had to drill new holes for the screws but I won't regret it. When they were succesfully installed into my guitar, they were rock solid. They're keeping my guitar in tune as any proffesional machine heads. And they look good! They made my guitar look more beautiful and expensive!
If you gonna replace your old machine heads I really recommend these! If you want to go for an vintage look and also want stable and reliable tuning, these will get the job done!
